SAFE OR VAULT LOCK.v

SPECIFICATION forming part of Letters Patent No. 427,140, dated May 6,1890. Application tiled January 16, 1888. Serial No. 260,838. (Nomodel.)

To all whom it may con/cern.-

Be it known that 1, CHARLES O. YALE, a citizen of the United States,residing in the city of Rome, in the county of Oneida and State of NewYork, have invented certain new and useful Improvements in Safe or'Vault Locks; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the iigures ofreference marked thereon, which form part of this specification.

My invention relates to an improvement in safe or Vault locks.

Itis the object of my invention to provide a safe-door without a holethrough the plates thereof and a lock for locking and unlocking l the Ydoor or any door to which it is adapted or applied.

In the drawings similar numerals of reference refer to like or similarparts in the several figures.

Figure 1 shows a section of a safe on a line substantially with theinner face of the door and my locking device mounted thereon, some ofthe similar parts there-oi` being removed or left out of the drawings.Fig. 2 shows an end view of a beveled gear-wheel and its shaft forrotating the bolt. Fig. 3 is a sectional view of an actuating-case, andshows a ratchetwheel and dogs -for actuating the locking device. Fig. 4is a detail view, partially in section, showing the actuating device andits connection with gear-wheel and rack for operating the bolt-work.Fig. 5 is a view of the side of the actuating-case nearest the boltwork,and shows a slide, pin, and lugs for adjusting or operating the dogstothe ratchetwheel. Fig. 6 shows a rack for rotating the bolts andengaged in a pin-wheel on the bolt for rotating the same. Fig. 7 shows abrokenout section of a section of the safe, taken on a line with A B,Fig. 8, and shows a bar carrying a portion of my locking device upon theinner face of the door. Fig. 8 shows a longitudinal cross-section of asafe-door and its jamb substantially on a line with C D of Fig. 1, and adevice for moving the door and a part ofthe bolt-work of my lockingdevice contained inside of the door. Fig. 9 is a detail View showingdevice for communicating rotary motion from one bolt to the other atyright angles thereto.

Heretotore bolts have been moved into position with the door for lockingand then the bolts thrown. It is one of the objects of my invention tocompound these two moveme'nts.

I provide in my locking device one or more bolts having a compoundmovement. Upon the inner surface of the door 1 is mounted a number ofbolts 2 2, 3 3, and 4 4. These bolts operate through a bar 5, secured tothe inner face of the door, and are adapted to be thrown or projectedback of the inside of the plates 6, which plates may be a portion of thebody of the safe. and drawing the bolts I provide a throw-bar 7, towhich bar are secured bolts 2 in such manner as to be thrown and drawnby and with the bar, but admit of their being rotated. The bolts 8 aresecured to bar 8, and are thrown and drawn by the movement of the bar 8,which movement is accomplished simultaneously with the movem entof theother bolts by means of rack 9 on an arm of bar 7 and the rack on arm 10of bar 8 and pinion 11, pivoted to the door and engaging in each of theracks.

Bolts 4 are drawn and thrown by means of lever 12, pivoted to the doorat 13. One end of lever 12 is forked and adapted to engage bolt 4 in agroove 14, so as to throw and draw the same without interfering with therotation thereof. The opposite end of lever 12 from that which engagesbolt 4 is provided with a slot 15. Pin 16:L of throw-bar 7 is adapted tomove in the slot 15 and actuate lever 12 as the throw-bar 7 is thrownand drawn, and thus simultaneously thro-w and draw bolts 4 with theother bolts.

For rotating the bolts or so many of them as it is desirable to rotate,means are provided. Bolts 2 are provided with pin-wheel 16, Figs. 1 and6, secured to the bolt and adapted to be engaged by movable racks 17,which racks are on movable bar 18, Fig. 1. For rotating bolts .4, Iprovide bevel gears 19 19, Figs. 1, 2, and 9, which gears engage eachother and are mounted on shafts 2O 20. Shafts 2O are mounted in bearings21 and pass into proper holes in the end of bolts 2 and 4, and have theends slotted, as shown in For throwing ICO . or drawn.

Means are provided for allowing a movement of the door while the boltsare being thrown or drawn. As a means of allowingof this movement, Iprovide in the outer ends of each of the bolts 2 and 4 and all of thebolts of the door, if desirable, recesses 23 and 24, Figs. 6 and 7.Recesses'23 and 24 in the ends of the several bolts are adapted toreceive raised projection or fence 25 of plate 6, Figs. 1 and 8, or somany thereof as are designed to receive the rotating bolts.

For the purpose of throwing and drawing the several bolts for securingthe door I provide the following means: Thepinion 2li, Fig. 4, pxvotedto the door, meshes into rack 27 on throw-bar 7 and is adapted to movethe same. Pinion 26 is provided with beveled gear-teeth adapted toengage beveled gearwheel 28 on a shaft 29, which shaft rotates in abearing in bar 5. On the opposite' end of shaft 29 from gear 28 ismounted ratchetwheel 30, Figs. 3, 4, and 5. Ratchet-wheel 30 1s adaptedto be engaged by either dog 31 or dog 32. Dogs 31 and 32 are pivoted at33 and 34, respectively, in a movable case or frame 35, Figs. 3 and 5,and are provided with slotted arms, as shown at 3G, Fig. 3. The dog andarm are adjustable with reference to each other, but are heldsubstantially in the relative position shown in Fig. 3 by spring 37.Spring 37 is intended to allow the dogs to pass the teeth oftheratchet-wheel 30 during the retrograde Vmovement of the ratchet-wheel.Dog 31 is thrown out of and dog 32 into contact with ratchet-wheel 30 bymoving vertically pin 38, which passes through the slot inv each of thearms of dogs 31 and 32 so far as the slotin case 35, through which thepin 38 passes, will permit; or both dogs may be thrown out of engagementwith the ratchet-wheel by moving the pin half-way. Pin 38 is secured inand moves with plate 39, Fig. 5, the pin passing along slot 40 in case35. Plate 39 moves in ways or guides 41 41, and is provided with ears orlugs 42 42 for the reception of the end of lever 43, Fig. 1, betweenthem. Lever 4 3 is pivoted to the door at 44, and is provided on theunder side with a projection 45, (shown in dotted lines,) adapted tocome in contact with projection 4G on throw-bar 7, (alsoshown in dottedlines in Fig. 1,) which projections while in contact are adapted to holdlever 43 in its upper or lower position. The end of the lever 43, whichis adapted to be engaged between lugs42, Figs. 1, 4, and 5, is broadenough to allow of the movement of the case 35, hereinafter described,without.

the lever or lugs being disengaged from each other. Case 35 fits movablyin a recess in bar 5, and is held in its normal position by 'projectionis provided at 62.

springs 47, Fig. 7. Case 35 is provided with lugs 48 48, Fig. 5, whichlugs are adapted to be engaged by lugs 49 49, Fig'. 1, on plate 50 whenthe door is closed or nearly so, which plate is secured in properposition on the body of the safe. 51 is an ordinary time-lock, which isadapted to operate tripper 52, which tripper operates catch 53. Catch 53is adapted to engage lever 54 by shoulder 55 thereon, resting uponshoulder 56 of the catch. Lever 54 is pivoted at 44 to the door. Theopposite end of lever 54 from that engaged by catch 53 is provided witha slot or opening 57 for the reception of projection 58 uponverticallymovable bar 18. Lever 54 and bar 18 vare raised or held up byspring 59, secured to the door at 60 and to the lever at 61.

Upon the under side of the bar 1 8 a lug or This lug is adapted toengage projection 63 on the inner face of the door and pass along theupper side of the same, down the right-hand end, along the other side,and up the left-hand end, passing entirely around projection 63 everytime the door is locked and unlocked. Projection 63 is secured to theinner face of the door and projects through slot or opening in throw-bar7 to such adistance that it may be engaged by projection 62 on the underside of bar 18. Bar 18 is held to throw-bar 7 by y guide or clasps 64 G4in such manner as to move with throw-bar 7, but ad mit of averticalmovement independent thereof. For moving the door out toallow'of the tongue and grooved jamb being disengaged from the tongueand grooved door, and to provide for the slight inward and outwardmovement for operating my locking device, I provide a vibra-ting hinge,as shown in Fig. 8. 65 isa vertical shaft made to vibrate, which hasfixed to it crank X. At 66 is a hole in the crank to admit the pintle67, which rotates therein, the pintle being secured to ear 68, which isfastened to the door. 69 is a lever-handle for partially rotating shaft65 and producing an inward and outward movement of the door through thecrank X. Ear 70 hinges shaft 65 to the body of the safe. Handle 69 willswing' around pin 71 out of the way of the door while open.

Gears 19,I prefer to provide with a cut-away portion, as shown in Fig.2, so as to admit of their being more readily placed in position in thelocking device.

The operation of my locking device is as follows: Starting with thelock, as shown in Fig. 1, in which position it is partially unlocked, Itake handle G9 and draw it out from the safe. This moves the edge of thedoor neXt to the hinges out of the jamb slightly, as shown in dottedlines in Fig. 8, the fence 25 on the plate 6 passing into the recesses24 in the ends of the safe-bolts. During this outward movement orvibration of the door just described projecting lugs 48 of case 35 areheld in contact with projections 49 on the jamb by the springs 47 actingbetween IOO IIO

the case 35 and the door. The case is thus held stationary withreference to the jamb while the door makes the slight outward movementor vibration just described. The dogs or pawls 31 and 32 being pivotedin the case 35 and the dog 31 in contact with rack or ratchet-wheel 30during the process of unlocking, and the ratchet-wheel 30 moving throughthe door, and the casing in which the dog 31 is pivoted beingstationary, the dog 31 will be retracted over the ratchet-face of thewheel in the outward movement or vibration of the door, and will engagea succeeding tooth in the ratchet-wheel 30 when the door has reached thelimit of its outward movement by the bottom of recess 24 coming incontact with the top of fence 25. Handle 69 is then forced back towardthe door, which lnovement forces the door back into the jambs, and thelugs 49, engaging lugs 48 of the case 35, prevent it passing inward withthe door; but the ratchet-wheel engaged by dog 31 must lnove positivelywith the door, so that as the door is forced inward the ratchetwheel 30is rotated. This rotates gear 28, pinion 26, and moves rack 27, carryingthe throwbar 7 backward and drawing or partially drawing bolts 2. At thesame time bolts 4 are drawn a like distance by pin 16a on throwbar 7acting on the inclined face of opening in the lever 12 and carrying thebolts 4 back, and bolts 3 are drawnv by the action of rack 9 and rack onarm 10 and pinion 11, as hereinbefore set forth. -As the door passesinto the jamb from its outward limit of vibratory movement to its innermovement the springs 47 between the movable casing 35 and the door areextended or stretched. The inward and outward movement of the door iscontinued, the dog gaining on the ratchetwheel with each outwardmovement until it has been sufficiently rotated by each inward movementto draw the bolts so that they will pass plate 6 and allow the door tobe fully opened. Vhen the door is unlocked, projection 46 has passed tothe right far enough to allow projection 45 of lever 43 to be passedupward byit, and projection 62 on the under side of bar 18 has passed tothe right far enough to allow it to be passed down the right-hand end ofprojection 63.

W'hen it is desired to lock the safe, the timelock is set and lever 43is passed up, so that projection 46 will pass along the lower side ofprojection 45 and hold lever 43 in its upper position. Bar 18 is drawndown by the operator moving the same with his hand while the door isopen until projection 62 will pass under projection 63. The raising oflever 43 throws dog 31 out of contact and dog 32 into contact with theratchet-wheel 30. The drawing down of bar 18 rotates all the bolts thatare designed to be rotated through the mechanism hereinbefore described,so that the recesses 23 in the bolts will coincide with the fence on theplate 6 when the door is closed. The downward movement of the bar 18also raises shoulder 55 up to and above shoulder 56. The door havingbeen swung into position for locking,handle 69 is moved in toward thedoor. This passes the door into the jamb and the lugs 49 on plate 50come in contact with lugs 48 on the movable case 35 and limit thefurther inward movement; but the casebeing sli ghtlyin advance of thedoor by reason of the springs 47 become stationary with reference to thejamb before the door has swung completely into the jambs, and the doorcontinues its inward movement after the casing 35 has become stationarywith reference to the j amb. The ratchet-wheel is carried against dog32, which produces a slight rotation thereol',

which rotation is communicated to the bolts,as

hereinbefore set forth, onlyin a reverse direction from the motion ofthe same parts hereinbefore described. After the door has been passedentirely into the jamb,the first time, the bolts will be thrown so thatthey will not pass the plate 6. Handle 69 is then drawn out, moving thedoor out of the jamb until its movement is limited by the top of thefence 25 coming in contact with thebottom of the recesses 23 in thebolts. During the outward movement of the door the case 35, with thedogs, is held back against lugs 49 by springs 47. While theratchet-wheel is carried out with the door, the door being again forcedback into the jamb, another slight rotation of the ratchet-wheel isproduced and the bolts thrownfarther out. This operation is continueduntil the bolts are fully thrown, at which time lug` 62 has passedentirely along and beyond the lower side of projection 63. As soon aslug 62 has passed Vby the end of projection 63 bar 18 is drawn upwardbythe action of the spring 59 until lug 62 is stopped directly oppositethe leftfhand end-of projection 63. The upward movement of bar 18 isstopped, as indicated, by shoulder coming in contact with shoulder 56.As the bar 18 is moved upward by the action of the spring 59 the bolts 2and 4 are rotated, and as the upward movement of the bar is stopped bythe catch 53 engaging the lever 54 the parts are so arranged that thepart 72 of the bolts will rest upon the top of the fence 25, and in thisposition movement ofl the door is prevented. At the time whenv the boltshave been entirely thrown projection 46 has passed entirely along thelower side of projection 45 and beyond the lefthand end thereof, andlever 43 has descended, throwing dog 32 out of contact and dog 31 intocontact with ratchet-wheel 30, in which position the parts are ready forthe unlocking process, as shown in Fig. 3. In these several positionsthe several parts remain until the time-lock 51 has moved tripper 52 andthrown catch 53 out of engagement with lever 54. Spring 59 then causesbar 18 to complete its upward movement, rotating the bolts untilrecesses 24 ofthe several bolts register with and are in a position toreceive fence 25, in which position there may be a slight vibra- IOO IIO

tory movement of the door, which movement will unlock the door, ashereinbefore set forth.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a door, a jamb, a bolt for locking the door in thejamb, having a recessed or cut-away portion of the projected endsadapted to admit of a vibratory movement of the door when the bolt isthrown, and the connecting mechanism between the jamb and the bolt,whereby the bolt may be thrown and drawn by the vibratory motion of thedoor.

2. The combination of a door, a jamb, a bolt for locking the door in thejamb and constructed and arranged to admit of a vibratory movement ofthe door when the bolt is thrown, connecting mechanism or gear ingbetween the jamb and bolt for throwing and drawing the bolt by vibratorymovement of the door, and time mechanism and a catch for securing thebolt in certain fixed position.

'3. The co1nbinatiou,with the door and j amb, of a bolt for locking thedoor in the jamb and the connecting mechanism for throwing and drawingthe bolts by the vibration of the door, substantially as set forth.

4. The combination of a door, a jamb, a rotating locking-bolt having oneor more recessed or cut-away surfaces on its projected end to admit of avibratory motion of the door when the bolts are thrown, a connectingmechanism between the door and jamb for throwing and drawing the boltsby the vibration of the door, and a catch and connections between it andthe bolt to secure the bolt from rotation between its locking andunlocking positions.

5. The combination of a door, a j amb, a bolt for securing the door inthe jamb, and a movable casing or frame mounted upon the door, adaptedto engage with the jamb before the door has fully entered the jamb, thecasing carrying a dog adapted to engage a rack connected with the bolt.
